Keywords: analog circuit design, digitally pr ogrammable analog circuits, electro- nic modules, PGA, CMOS digital potentiomet ers, direct digital synthesis, PLL
Abstract: In this paper we present a specific electronic system for analysis and design of digitally programmable analog circuits. The created electronic system is with module structure and envelops specific circuits such as programmable gain amplifiers (PGAs), attenuators, analog circuits with CMOS digital potentiometers, active filters, direct digital synthesis (DDS) waveform generators, digital circuits with microcontroller, etc. In particular the system cons ists of the following six separate electronic modules: (1) electronic circuits with CMOS digital potentiometers; (2) electronic circuits with monolithic PGAs; (3) program mable active RC and SC filters (4) monolithic direct digital synthesis (DDS) generators; (5) digitally-controllable audio electronic systems; (6) HF PLL synthesizer. The electronic system, presented here, is intended for laboratory practice with students in Electronics in the Technical University of Sofia.
